incorrect nested loop expression

[clkao]

res = for i in [1 to 10]
  [x] = [ z for z in [1 to 2] ]
  x + i

this returns an array of array, while the inner loop was just for looking something up rather than constructing another level of nested loops.

What about:

res = for i to 9
  while 0 => while 0 =>  
  i

reopening since it's still broken (a bit "deeper", but it indeed needs to work like makeReturn)
